Up until today I"ve had one issue where the hydraulics didn"t work, it was late last fall and they came right back. Running a 2 point cycle bar and rigged it yesterday for hyd cylinder for bar lift. Had a bit of fussing to get it to start cycling in a bit but when I messed with the S/D position setting on the valve body it took off it worked fine. I assumed it was air trapped in the system. I had also had the aux. valve body(near the front right corner of the seat) apart to replace the handle/shaft and not tried it before this cylinder addition. So as everything seemed hunkydorey I parked it, noticed I had a cylinder line loose and leaking, tightened that and fixed the sections on the cycle bar. When I put the cycle back together I get absolutely nothing from the hydraulics. Topped the fluid. I don't hear the normal noise from the pump, and get no movement, nothing. Moved both 2 pt. lift levers and cyclebar lift levers, nothing. Buddy suggested plugged screen so I pulled the line pair from tank to the pump and it seemed to drain fine. Blew back with 50psi in the supply(big) port, no sign of a restriction.
Any suggestion as to next step? I see something about a pressure regulator valve in the manuals but don"t understand how it works enough to do some testing on that??? Guess I"ll pull the top f the tank in the morning and see what I can see for a screen. Help? Supposed to start cutting today of course.
